Stanislav Lisov was detained in Barcelona airport on Jan. 13 as part of an FBI search for “Russian hackers,” his wife Darya Lisova told the news outlet.

The couple, who live in the southern Russian city of Taganrog, were visiting the country on holiday, she said.

“As soon as we got out of the car, we were approached by two police officers who showed us their badges and told us that my husband was under arrest,” Lisova told RT. “Then they began to check his phone, tablet and laptop.”
